People with eating disorders, especially those with anorexia nervosa, have an increased risk of death, a new study indicates.

There were a total of 17,272 patients in the studies, which reported 755 deaths. The meta-analysis revealed that for each 1,000 person-years, 5.1 deaths occurred among anorexia patients (1.3 of which were suicide), 1.7 deaths among bulimia patients, and 3.3 deaths among patients with other eating disorders. (A meta-analysis pools and analyses statistical data from different studies investigating similar questions.)

The standardised mortality ratio (the number of actual deaths compared with the number of expected deaths) was 5.86 for anorexia, 1.93 for bulimia, and 1.92 for other eating disorders.
